Company Information
Shandong Guangtongbao Pharmaceuticals Co.,Ltd
  Shandong Guangtongbao Pharmaceuticals Co., Ltd( Which Belonged to Shandong Guangtong  Group.)is the largest manufacturer of chlorophyll series products and vitamin k1 series product. Based on that, our business scope involves fine chemicals, pharmaceuticals, foodstuff, fodder,home textile and import and export business.

    The predecessor of our company is Shandong Province Qingzhou Biological & Chemical Institute for Mulberry Silkworm Eggs established in 1985; In 1992, this Institute established a joint venture with Hong Kong Hualu Silk Co., Ltd. – Shandong Guangtong Chlorophyll Co., Ltd.; In 2003, we established a stock company - the present Shandong Guangtongbao Pharmaceuticals Co., Ltd.. From 1977, we started to make research on chlorophyll series products. After thirty years’ efforts, we now have several series, nearly twenty products, ie. chlorophyll paste, oil-soluble  chlorophyll, sodium copper chlorophyllin, sodium magnesium chlorophyllin, sodium ferrous chlorophyllin, sodium zinc chlorophyllin, vitamin k1, natural phytol and menadione. Our company became a leading manufacturer all over the world which has annual turnover of more than 300tons of chlorophyll paste, more than 30tons of sodium copper chlorophyllin and more than 4000kgs of vitamin k1 from a small workshop. Meanwhile, we devoted ourselves to the demand from the customers. Sequentially, we solved the technical problem which regulated in Law of European and USA, i.e., heavy metals, solvents residues and shade. We also solve the application of chlorophyll in acidity condition. It also took us more than 2 million to buy a set of world-advanced analysis instruments from Shimadzu company, i.e. UV ultraviolet spectrophotometer, atom-absorptance flame spectrophotometer, high performance liquid chromatograph, gas chromatograph which guarantee the quality of our products. We also went through Kosher Certification for Jews, GMP Certification for domestic pharmacy and DMF for Europe market according to the different demand from the customers. All these actions raised our prestige, enlarged our shares in domestic and abroad market and guarantee our leading position on terms of product quality in same cycle.

   Relaying on the advantage of management,scale, technology and human resources,we developed foodstuff,fodder,home textile. All these products develop fast and lay a firm foundation for a company with a large scale and assorted products.
   Sticking to the principle of “Abiding by honest and credit, benefit one another, develop jointly”, we sincerely welcome all the friends and companies at home and abroad to communicate and cooperate with us for brighter future.
